If you are an adult woman who has had unprotected sex before, you need to take an early pregnancy test to rule out early pregnancy. After pregnancy, the hormone level in your body increases and breast enlargement occurs, so that you are well prepared for breastfeeding later, in which case your breasts will appear swollen and uncomfortable. If early pregnancy is ruled out, hormonal disorders in the body can also lead to irregular menstruation, and breasts are rich in hormone receptors, so they can lead to breast hyperplasia and swelling and discomfort, which is usually caused by excessive stress, mental tension, overwork, disease, etc. It is also necessary to go to the hospital for examination. The actual reason for this is the fact that you can’t get a lot of money from the company.
